Intel's Struggles: From Dominance to Decline

The x86 instruction set, once central to personal computing, is now seen as a hindrance to the PC industry, contributing to Intel's decline. With Microsoft and Qualcomm's support for Arm in 2024 and Nvidia's upcoming advancements, the x86 architecture faces obsolescence. Intel's dominance, maintained through questionable practices, is challenged by market shifts and competition, notably from Apple's transition to Arm. This marks a significant inflection point in computing history.

"Zhaoxin's KX-7000 CPUs: High-Performance Eight-Core Processors for China"

Zhaoxin has unveiled its Kaixian KX-7000 series of x86 CPUs, featuring up to eight general-purpose cores running at 3.70 GHz. The new CPUs are based on the Century Avenue microarchitecture and offer improved CPU core design, out-of-order execution engines, and back-end execution units. They also include a new integrated GPU design with four times the performance of its predecessor. The CPUs utilize a chiplet architecture similar to AMD Ryzen processors and provide 24 PCIe 4.0 lanes, USB4 roots, USB 3.2 Gen2 roots, USB 2.0 roots, and SATA III ports. The KX-7000 processors will be available in both BGA and LGA packages and are expected to be used in client and embedded PCs in 2024.

Linux 6.4 brings major performance improvements and updates for various file systems and hardware.

Linus Torvalds has written new code for the Linux 6.4 kernel, focusing on cleaning up the x86 memory copy code, particularly for user accesses. The code replaces legacy markers with modern markers for micro-architectural support, improving memory copying and clearing. The update is mostly about user memory accesses, as in-kernel cases are done by the compiler. The Linux 6.4 merge window remains open for more feature code.
